2-3-3 DeviceNet Connection
This section explains the pin allocation of the DeviceNet connector for the
DeviceNet network. For further details on how to connect the DeviceNet net-
work, refer to DeviceNet Operation Manual (W267).
2-3-4 I/O Specifications
The following tables provide specifications and circuits for the I/O and
Encoder connections.
Digital Inputs
Input Response times
The response times given in the following table are the times between the
change in the input voltage and the corresponding change in the IN parame-
ter.
These times are depending on the MC Unit’s Servo Period and the priority of
the corresponding BASIC task and they include the physical delays in the
input circuit.
Print Registration delay time
The print registration is used to capture position data in hardware triggered by
either a digital input or the Z-marker encoder signal. For the encoder axis 1
the print registration delay times are given by
